a lot of these kids are leaving for things completely unrelated to football. i'd say at least half, if not more. just looking back to the 2017 and 2018 recruiting classes, 9 left in total (not counting nfl draft, graduates, or still enrolled) - 3 left because they were from the west coast and had a culture shock/depression and left before end of their first year on campus, 1 was kick out due to crime, 1 never enrolled and went juco. so that's 5 of the 9 for non-football reasons. 1 qb left being behind hurts, tua and mac, 1 wr left (same class as jeudy, ruggs and smith), 1 kicker that started 2 years and was beat out by frosh and then left, and 1 lb was suspended from team (undisclosed) and then left, which likely isn't football reason but i'll leave it here anyway since we don't know.
